Sunny Windypool-Solarview is the baby daughter of Astronov and Neptunia, seen in The All New Fairly OddParents!. Sunny is one of the unique fairy babies, since she was born from a female fairy, which occurs rarer than birth from male fairies.
Sunny, as the name implies, is a fairy baby with an upbeat attitude and good sense of humor. Within a week of her birth, she was able to speak English properly. Sunny likes to watch children shows. She also enjoys playing with the little children in the neighborhood, her best friend, Poof (whom she has a secret crush on), and, most notably, her mother, Neptunia, whenever she's not busy, and sometimes her father, Astronov. Sometimes, when something very bad happens, it causes Sunny to cry, which can also happen if something upsets her. Sunny also speaks fluent Japanese. Her voice is similar to Jenny Wakeman/XJ-9 from My Life as a Teenage Robot, except slightly higher.
Sunny is shaped like a ball. She wears green pajamas, has green-blue hair with a ponytail and orange eyes.
When grown up, Sunny has her hair tied into two pigtails, wears a green dress with short sleeves and a short skirt, white socks and black shoes.
When disguised as a pet, Sunny takes the form of a cyan hedgehog.
